I have discovered that chloride of ammonia, or chloride of soda, or an equivalent chloride compound, bisulphate of mercury, and glycerine, when properly mixed and me chanically held together, form a compound which possesses many advantages for charg ing' dry voltaic cells. In the formation from the materialsnamcd of a dry battery I obtain good results by makin a saturated solution of chloride of ammonia by dissolving the same in water and addin thereto a quantity of crystal s ol' bisulphate of mercury not exceeding one fourth by weight of the ammonia employed. To this saturated solution. of chloride of ammonia I add a quantity of glycerine equal to five per cent by weight of the water employed in makin said saturated solution. I then saturate pieces of asbestus with the chloride of ammonia, bisulphate of mercury, and glyc erine compound thus formed, and pack the saturated asbestus between and around the positive and negative plates or elements of the battery. This having been done, I attach conducting wires to the said positive and negative elements, and complete the closure of the containing box of the battery in any suitable manner. It bisulphate of mercury were not present in said battery compound the oxygen would be liberated, hydrogen would collect upon the surface, and in the pores of, and polarize, the carbon element. The polarization of the carbon element is prevented by the presence of bisulphate of mercury which causes the oxygen of the chloride of ammonia and bisnlphate of mercury c mpound to combine with the liberated hydrogen of said compound, and form water, and prevent the deposition of hydrogen gas upon the negative element of the battery. The otfice of the glycerine to indefinitely maintain sutficient moisture in the battery, to cause the substances of the battery compound to freely act, chemically, to sustain the action of the battery.

I do not confine myself to the exact proportions of chloride of ammonia, bisulphate of mercury, and glycerine above described, as it will be umlerstood that the proportions named may be varied without departing from my invention.

l'laving' thus described my invention, I claim- 1. A battery compound for a dry voltaic cell consisting of chloride of ammonia, or an equivalent chloride compound, bisulphate of mercury, and glyce'rine.

2. In a dry voltaic cell, in combination, a containing vessel, positive and negative elements contained therein, and a battery compound consisting of chloride of ammonia, or an equivalent chloride compound, bisulphate of mercury, and glycerine, contained within.

said vessel and in contact with said elements,

specified.

In testimony that I claim the foregoing as my invention I have hereunto signed my name this id day of April, A. D. 1888.
